Question

我有6个不同的表，当选择其中一个中的行时（在regionsFirstTable中，它对哪一个很重要）我希望它们执行一个segue。 regionsFirstTable的代码工作正常，但对于其他部分却没有 - segue只是不起作用。我知道它太乱了，但答案应该放在表面上。

- (void)tableView:(UITableView *)tableView 
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

if (tableView == self.regionsFirstTable) {
    {     if (indexPath.row==0)
        if (indexPath.section==1) {
            [self performSegueWithIdentifier:@"toAfricanFS" sender:indexPath];
        } else {
            [self performSegueWithIdentifier:@"toAfricanFS" sender:indexPath];
        }
        if (indexPath.row==1)
            if (indexPath.section==1) {
                [self performSegueWithIdentifier:@"toAsiaFS" sender:indexPath];

            } else {
                [self performSegueWithIdentifier:@"toAsiaFS" sender:indexPath];
            }
        if (indexPath.row==2)
            if (indexPath.section==1) {
                [self performSegueWithIdentifier:@"toEuropeFS" sender:indexPath];

            } else {
                [self performSegueWithIdentifier:@"toEuropeFS" sender:indexPath];
            }
        if (indexPath.row==3)
            if (indexPath.section==1) {
                [self performSegueWithIdentifier:@"toLatinFS" sender:indexPath];
            } else {
                [self performSegueWithIdentifier:@"toLatinFS" sender:indexPath];
            }
        if (indexPath.row==4)
            if (indexPath.section==1) {
                [self performSegueWithIdentifier:@"toNorthAmericaFS" sender:indexPath];
            } else {
                [self performSegueWithIdentifier:@"toNorthAmericaFS" sender:indexPath];
            }
    } //Dealing with the first UITableView, it works

    if (tableView == self.africaFirstTable) {
        [self performSegueWithIdentifier:@"fromAfricatoDone" sender:indexPath];
    } 
    if (tableView == self.asiaFirstTable) {
        [self performSegueWithIdentifier:@"fromAsiatoDone" sender:indexPath];
    } 
    if (tableView == self.europeFirstTable) {
        [self performSegueWithIdentifier:@"fromEuropetoDone" sender:indexPath];
    }
    if (tableView == self.latinAmericaFirstTable) {
        [self performSegueWithIdentifier:@"fromLatintoDone" sender:indexPath];
    } 
    if (tableView == self.northAmericaFirstTable) {
        [self performSegueWithIdentifier:@"fromNorthAmericatoDone" sender:indexPath];
    } //This whole thing is not working as it should be
}
}

提前致谢！

P.S。我的所有表只有一个indexPath.section

在您的第一个{之后看起来有if个太多，因此if ( tableView == self.northAmericaFirstTable)的所有检查都没有达到，因为它全部嵌套在if (tableView == self.regionsFirstTable)中阻止

编辑：

这是固定代码，理论上

- (void)tableView:(UITableView *)tableView 
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

if (tableView == self.regionsFirstTable) {
     if (indexPath.row==0)
        if (indexPath.section==1) {
            [self performSegueWithIdentifier:@"toAfricanFS" sender:indexPath];
        } else {
            [self performSegueWithIdentifier:@"toAfricanFS" sender:indexPath];
        }
        if (indexPath.row==1)
            if (indexPath.section==1) {
                [self performSegueWithIdentifier:@"toAsiaFS" sender:indexPath];

            } else {
                [self performSegueWithIdentifier:@"toAsiaFS" sender:indexPath];
            }
        if (indexPath.row==2)
            if (indexPath.section==1) {
                [self performSegueWithIdentifier:@"toEuropeFS" sender:indexPath];

            } else {
                [self performSegueWithIdentifier:@"toEuropeFS" sender:indexPath];
            }
        if (indexPath.row==3)
            if (indexPath.section==1) {
                [self performSegueWithIdentifier:@"toLatinFS" sender:indexPath];
            } else {
                [self performSegueWithIdentifier:@"toLatinFS" sender:indexPath];
            }
        if (indexPath.row==4)
            if (indexPath.section==1) {
                [self performSegueWithIdentifier:@"toNorthAmericaFS" sender:indexPath];
            } else {
                [self performSegueWithIdentifier:@"toNorthAmericaFS" sender:indexPath];
            }
    } //Dealing with the first UITableView, it works

    if (tableView == self.africaFirstTable) {
        [self performSegueWithIdentifier:@"fromAfricatoDone" sender:indexPath];
    } 
    if (tableView == self.asiaFirstTable) {
        [self performSegueWithIdentifier:@"fromAsiatoDone" sender:indexPath];
    } 
    if (tableView == self.europeFirstTable) {
        [self performSegueWithIdentifier:@"fromEuropetoDone" sender:indexPath];
    }
    if (tableView == self.latinAmericaFirstTable) {
        [self performSegueWithIdentifier:@"fromLatintoDone" sender:indexPath];
    } 
    if (tableView == self.northAmericaFirstTable) {
        [self performSegueWithIdentifier:@"fromNorthAmericatoDone" sender:indexPath];
    } //This whole thing is not working as it should be
}

performSegueWithIdentifier if语句不起作用
